army-14,

f properly grip the block of slateand as the shaft 9 is continued to rotate, said block` of slate will be dragged along the bottom of the ytunnel to a point adjacent the forward end ofthe beam B and will then be raised fromthe bottom of the tunnel. A conventional type of pawl-and ratchetV as indicated at11'8 serves to hold the shaft 9 against retrograde movement. Continued rotation of the shaft `QinCidentalto the contact ofthe grapplek G with the undersurfaceof the beam B results in the upward swingingmovement ofthe forward end of the `beam to the height,

desired., The members M and M may then beswung laterally so that the block of slate k'carriediby the grapple maybe dropped within a gob or goave or'the like. It will be self-evident that by reversing the rotation: ofv

the .shaft 9` the arms Hof the grapple Gr may be readily disengaged from the block of slate.

After the blocks of slate have 'been re-i.

moved fromthe faceor the like of a tunnel and it is desired to remove the Ene particles Vof dirt or other refuse, the chain 11 is disengaged from the grapple G and the shovel S securedlto the forward end portion of the beam B. vTheY shovel S isof the well known scraper` type and is mounted for swinging vmovement between .the arms`20. The rear end portions ofthe arms 20 are arranged in parallelism. andare disposed longitudinally of the beam l and in contact with the outer faces ofthe side flangesa. The arms 20 are secured tothe beam B or more particularly the anges a thereof by the bolts 2l arranged in spaced relation longitudinally of thebeamB.K N 'f ,Suitably secured'to the trunnions 22of the shovel S is the upstanding ybail 28 vwith which' the chain 11 is adapted to be con- .y nectedso that the beam B may be moved upwardly after the Y shovel S v has 'been' I for longitudinal Imovement independently loaded. f

Pivotally engaged with onev of the -bolts21 is a latch member 24.coacting withlthe shovel v fS to hold the same against swinging or dumping movementv relative to the arms 2O. Engaged with the latch is a flexiblel membery 25 of' suitable length and ywhich 'permits the operator to release the latch when-.it is desiredY that 'the loadfcarried bythey shovel Sxbe dumpedy after said shovelt has `been suitably elevated or positioned. r

Fixed to the shaft 8 between the arms 2 of the member M and between the side flanges a ofthe beam B is the chain block 26 over which is directed the chain 27 secured tothe rear end portion of the beam B. Upon proper rotation of the shaft 8 throughthe medium of the crank 28 or the like, the beam B--will be moved forwardly to properly force the shovel S into the material to be transported and the slots 7 in the flanges a of the beam B are of suiiicient length to permit this operation.

The shaft V8 is held against retrograde movement ,through the medium of the conventional pawl and ratchet as indicated at 29. In order to throw'the pawl into inoperative postion when it is desired to permit the beam B to fall downwardly, I provide the vertically disposed member 30 mounted for rocking movement and suitably supported by one of the arms 2 of the member' M and which is moved upwardly under the influence of the foot pedal 31. The member 30 isV also provided with the brake 32 adapted to frictionally engage the side flange a of the beam B to retard the downward movement of the beam. The member 30 is alsoprovided with a finger or extension 83 whichengages beneath the chain 27 upon.

upward movement ofthe member so that said chain will be disengaged from the block wheel 26 so that the shaft .8 will not rotate as they beam B drops down and thereby eliminates any possibility of injury by thel crank. 28.

From the foregoingV description, it is thought to be obvious that a mine apparatus `constructed in accordance with my invention is particularly well adapted for usev by reason ofthe convenience and facility with which it may be assembled and operated and it will also be obvious thatmyy invention is susceptible of some change and modification without departing from the principles andy spirit thereof and for this reason 1 do not wish to be understood as limiting myself t0 the precise arrangement and formation of the several parts herein shown in carrying out my invention in practicel except as hereinafter claimed.
